"The Air Duster can was a great buy. I needed to clean out the dust from INSIDE my computer case and this can did just that. I was a little dubious as to how good it would be as the online search listed products at double the price. I completed the job and there is still air in the can. Great value. The only point I would make to anyone using the product is to wear a glove to insulate your hand as the can becomes very COLD very quickly!"
